Dlctyot a dlyaricata Lamouroux. Common in grass beds and on 

 ttue algal plain in 3 to 23 m depth,. Reported to 55 m 

 deptfi by Taylor (1960). Randall 0-964) found D. divaricata 

 in the s^tomach contents of the queen concK, Strombus gigas 

 and the following fishes (Randall, 1967): Acanthurus 

 b ahianus , A. coeruleus , Cantherhines macroceru and C^. pullus . 

 On the algal plain, Acanthurus b ahianus , A. coeruleus , 

 A. chirurgus , Eupomocentrus partitus , Can thig aster rostrata, 

 Pomo can thus arcuatus , Sparisoma aurof renatum , S_. viride 

 were seen eating this species. 



Dictyota indica Sonder in Kutzing. Common on the algal plain 

 mixed with other algae in 18 to 23 m depth. Occurs in 

 various parts of the Caribbean, reported by Taylor (1960) 

 to 27 m depth. Randall (1964) found D. indica in stomack 

 contents of the queen conch., Strombus gigas . 



Dictyota linearis (C. Agardh) Greville. Common mixed with other 

 algae and epiphytic on sea grasses in 8 to 22 m depth,, in 

 grass beds and throughout the algal plain. Randall (1967) 

 reported Kyphosus sectatrix as a consumer. 



Ectocarpus rhodochortonoides Borgesen. Found only on the 



exterior of the TEKTITE habitat, but probably present on 

 other hard surfaces. Originally described from the Virgin 

 Islands (Borgesen, 1941) from plants found in exposed places 

 in the littoral region. Randall (1967) reported Ectocarpus 

 sp. in the stomach contents of Diplodus caudimacula and 

 Acanthurus coeruleus , and it is likely that all Ectocarpus 

 species are regularly browsed. 



Giffordia conif era (Borgesen) Taylor. Growing in the habitat, 

 and on Anadyomene stellata in 12 and 22 m depth. Originally 

 reported from St. Croix, Virgin Islands (Borgesen, 1914). 



Giffordia indica (Sonder) Papenfuss and Chihara in Papenf uss . 

 Obtained from the exterior of the TEKTITE habitat, 

 experimental cages, a dead sea fan, dead coral heads, sea 

 grasses and rocks in 5 to 20 m depth. Reported by Taylor 

 (1960) from shallow water to 20 m depth. Probably grazed 

 by the many species observed eating filamentous algae, 

 and definitely identified from a sea fan where Scarus 

 croicensis was actively browsing.
